I use this Linux distribution on a Panasonic CF-52 (i3) Toughbook.
I love this KDE tuned Linux distribution. Pure 64bit, and It's independent from USA :-) (not made in USA, something that is important for world citizens because of some weird privacy / human rights -ignoring usa laws these days).
It's sort of Crunchbang but then with KDE, and not based on Debian, but forked from Arch (Crux) Linux.
It's a bit new to have only KDE & QT programs (for example no Gimp that is depending on Gnome).
But it's very nice to use. Not for Linux beginners, because the installation GUI needs some maintenance.
Also keep in mind, this distro works better on a real machine, then on a virtual machine ;-P (people who try to install on virtual machines have more complains then people who install it on real hardware)
